FURNACE-CHARGING APPARATUS.

SPECIFICATION forming part of Letters Patent N 0. 698,768, dated April29, 1902.

Application filed November 21, 1901: Serial No. 83,104. (No model.)

To all whont it may concern:

Be it known that I, SAMUEL S. TALES, of Munhall, Allegheny county,Pennsylvania, have invented a new and useful Furnace- ChargingApparatus, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, formingpart of this specification, in which Figure l is a sectional sideelevation, with the parts broken away, showing furnacecharging apparatusprovided with my improved grip-bar. Fig. 2 is an enlarged sideelevation,partly broken away,of the grip-bar. Fig. 3 is a top plan viewof the same, and

Fig. 4 is a cross-section on the line IV IV of Fig. 2.

My invention relates to the charging of furnaces and is designed toprevent the rapid destruction from heat of the grip-bar by which thebillet, bloom, or charging box is carried into or out of thefurnace-chamber. Heretofore in the use of such apparatus the gripbarsmust be replaced at frequent intervals, as they soon warp, crack, anddeteriorate under the heat to which they are subjected. My inventiongreatly lengthens the life of these bars; and it consists in providingthem with open-top cavities or pockets which are supplied with water orother cooling fluid.

It also consists in a construction of the bar as hereinafter describedand claimed.

In the drawings, 2 represents part of the frame of the chargingmachine,supported from lever 3.

4 is the grip-bar, pivoted at 5 and having a tail portion 6, pivoted toconnecting-link '7. The rear portion of this bar is cored out forlightness, as shown at 8 in Figs. 2 and 3, while its front portion iscast or otherwise formed with a series of pockets 9, havingseparatingpartitions 10 extending transversely between them. -Upperslots or holes 11 lead through the top of the bar into the pockets, thewater or other cooling fluid being supplied through these slots by meansof a supply-pipe 12 or other means when the bar is outside the furnace.

13 is the movable gripper, which is supported upon guides 14, extendingalong the grip-bar, 15 being an electric motor upon the charging-machineacting through gearing 16 upon screw mechanism 17 to bind or release thebillet-box or other element to be inserted or removed.

In using the apparatus the metal or box is gripped in the usual manner,the movements of the machine being those ordinarily employed. Thepockets are kept supplied with water by feeding fluid into them when thepeel or bar is outside the furnace.

The advantages of my invention result from the long life of the bars,owing to the water cooling and from the simplicity of the cooling means.On account of the difierent movements of the grip-bar it would be Verydifficult to cool it by means of fluid supply and exhaust pipes leadingto cavities in the bar.

Many changes may be made in the form and arrangement of thecharging-machine, the bar, and the means for supplying fluid withoutdeparting from my invention.

I claim 1. In charging apparatus, a grip-bar having a cavity with aclosed bottom and arranged to contain apool of cooling fluid;substantially as described.

2. In charging apparatus, a grip-bar havin g a plurality of separatedpockets arranged to contain water; substantially as described.

3. In charging apparatus, a grip-bar having a cavity with a closedbottom to receive a cooling fluid, and provided with a top feedopening,and a water supply arranged to feed water to the cavity when thegrip-bar is outside the furnace; substantially as described.

In testimony whereof I have hereunto set my hand.

SAMUEL S. WALES.
